[0002] Graphite is a natural mineral composed of carbon elements, a special material with good thermal conductivity, high temperature resistance and self-lubrication. It is an excellent thermal conductive material and lubricant, and is often used in the manufacture of conductive materials, thermal conductive materials and lubricants, etc. When processing graphite on a lathe, the key lies in selecting appropriate cutting tools and cutting parameters, keeping the workpiece and the cutting tool clean, controlling the cutting accuracy, and ensuring efficient and precise processing. The lathe processing of graphite is widely used in the fields of electric power, metallurgy, aerospace, etc., providing important support for the production of high-quality graphite products. Traditional lathes can only process rotary graphite materials and cannot be used when graphite raw materials are square in some specific fields, so the applicable range is small. Content of the Utility Model

A guide rail is arranged on the headstock, and a moving frame is slidably arranged in the guide rail. Two clamping blocks are slidably arranged on the moving frame relatively for clamping graphite raw materials; the chuck is used for clamping a rotating shaft, and a reciprocating assembly is arranged at the end of the rotating shaft for making the moving frame slide reciprocally along the guide rail.

[0009] An installation groove is formed on the end face of the headstock. One end of the guide rail is fixed to an installation plate, and the other end of the installation plate can be arranged in the installation groove; a plurality of first threaded holes are formed on the outer surface of the headstock, and the first threaded holes communicate with the installation groove.

[0014] Figure 2 is a structural schematic diagram of the reciprocating assembly. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0016] As Figures 1 to 2 shown, the tool for processing graphite square materials on the lathe of the utility model includes a chuck 11 rotatably arranged on a headstock 10. A guide rail 21 is arranged on the headstock 10. A moving frame 22 is slidably arranged in the guide rail 21. Two clamping blocks 23 are slidably arranged on the moving frame 22 for clamping graphite raw materials; the chuck 11 is used for clamping a rotating shaft 24. A reciprocating assembly 30 is arranged at the end of the rotating shaft 24 for making the moving frame 22 reciprocate along the guide rail 21.

[0017] When it is necessary to process graphite raw materials into squares, the guide rail 21 is fixed on the headstock 10, and the rotating shaft 24 is clamped by the chuck 11. The headstock 10 drives the chuck 11 and the rotating shaft 24 to rotate, and the reciprocating assembly 30 at the end of the rotating shaft 24 drives the moving frame 22 to reciprocate along the guide rail 21, so that the two clamping blocks 23 and the graphite raw material therebetween reciprocate relative to the turning tool, and the plane processing of the graphite raw material is realized through the feeding movement of the turning tool. Then, the processing plane of the graphite raw material is switched to process graphite square materials, expanding the scope of application.

[0018] Among them, the headstock 10 is arranged on the lathe bed, and a turning tool is provided at a position corresponding to the headstock 10. The turning tool can perform a feeding movement in the horizontal direction and the axial direction of the headstock 10. When the moving frame 22 reciprocally slides along the guide rail 21, the turning tool performs linear machining on a plane of the graphite raw material. By the turning tool performing a feeding movement in the horizontal direction, surface machining of a plane of the graphite raw material is achieved, so that multiple surface machinings of the graphite raw material can be carried out. The structure of the lathe is prior art and will not be elaborated here. Those skilled in the art can select a turning tool that meets the processing requirements according to actual applications to achieve surface machining of the graphite raw material.

[0019] Among them, a clamping rod 12 is slidably arranged along the radial direction of the chuck 11. A mechanism for driving the clamping rod 12 to slide is arranged inside the chuck 11. Three clamping rods 12 are arranged along the circumferential direction of the chuck 11. The end of the clamping rod 12 can contact the workpiece to be clamped and perform a clamping process. Its structure is prior art and will not be elaborated here.

[0020] Preferably, the reciprocating assembly 30 includes a half gear 31 and a rack 32. The end of the rotating shaft 24 is fixed with the half gear 31. The half gear 31 is arranged inside the moving frame 22. Two racks 32 are oppositely arranged on two side surfaces inside the moving frame 22. The half gear 31 alternately meshes with the two racks 32.

[0021] The headstock 10 drives the chuck 11 and the rotating shaft 24 to rotate, driving the half gear 31 to rotate. The half gear 31 alternately meshes with the two racks 32 to drive the moving frame 22 to reciprocally slide along the guide rail 21.

[0022] Among them, the number of teeth of the half gear 31 and the rack 32 satisfies: when the half gear 31 meshes with one rack 32, it disengages from the other rack 32. Immediately after the half gear 31 disengages from one rack 32, it starts to mesh with the other rack 32. The central angle of the half gear 31 with teeth is preferably less than or equal to 180°. The gear parameters such as the module of the half gear 31 and the rack 32 are the same so that the two can mesh and drive each other.

[0023] Of course, a reciprocating assembly 30 with other structures can also be used for replacement to drive the moving frame 22 to reciprocally slide along the guide rail 21. For example, a disc is fixed at the end of the rotating shaft 24, and an eccentric pin is provided on the disc. A groove corresponding to the pin is opened on the moving frame 22. Another example is that a crank is fixed at the end of the rotating shaft 24, and a connecting rod is arranged between the crank and the moving frame 22.

[0024] Preferably, the rotating shaft 24 is rotatably arranged on the moving frame 22 through a support rod 33.

[0025] Preferably, two guide rails 21 are symmetrically arranged about the axis of the headstock 10.

[0026] Preferably, an installation groove 41 is formed on the end face of the main spindle box 10. One end of the guide rail 21 is fixed to the mounting plate 42, and the other end of the mounting plate 42 can be arranged in the installation groove 41. A plurality of first threaded holes 43 are formed on the outer surface of the main spindle box 10, and the first threaded holes 43 communicate with the installation groove 41. A locking bolt 44 is correspondingly arranged in the first threaded hole 43 for fixing the mounting plate 42 in the installation groove 41.

[0027] To achieve the detachable fixation of the guide rail 21 and the main spindle box 10.

[0028] Preferably, two clamping seats 51 are relatively fixed on the moving frame 22. A second threaded hole 52 is formed in the clamping seat 51, and a clamping bolt 53 is correspondingly arranged in the second threaded hole 52. A clamping block 23 is rotatably arranged at the end of the clamping bolt 53. A guide rod 54 is fixed on the clamping block 23, and a guide hole 55 is correspondingly formed in the clamping seat 51. The guide rod 54 slides along the guide hole 55.

[0029] The rotation of the clamping block 23 is restricted by the cooperation of the guide rod 54 and the guide hole 55. By rotating the clamping bolt 53, the two clamping blocks 23 move relatively to clamp the graphite raw material.

[0030] Preferably, a groove 56 is formed on the surface of the clamping block 23 away from the clamping bolt.

[0031] To achieve better clamping of the graphite raw material.

[0032] Among them, anti-slip lines are formed on the surface of the clamping block 23 away from the clamping bolt and in the groove 56.

[0033] The working principle of the present utility model is as follows:

[0034] When it is necessary to process the graphite raw material into a square shape, the other end of the mounting plate 42 is placed in the installation groove 41 and locked by the locking bolt 44 to fix the guide rail 21 on the main spindle box 10. Rotate the clamping bolt 53 to make the two clamping blocks 23 move relatively to clamp the graphite raw material. By controlling the sliding of the clamping rod 12 on the chuck 11, the rotating shaft 24 is clamped. Start the main spindle box 10 to drive the chuck 11 and the rotating shaft 24 to rotate, drive the half gear 31 to rotate, and the half gear 31 alternately meshes with the two racks 32 to drive the moving frame 22 to reciprocate along the guide rail 21, so that the two clamping blocks 23 and the graphite raw material therebetween move reciprocally relative to the turning tool, that is, the turning tool performs linear processing on a plane of the graphite raw material. By making the turning tool perform a feeding movement in the horizontal direction, surface processing of a plane of the graphite raw material is achieved. Then, switch the processing plane of the graphite raw material, so that multiple surfaces of the graphite raw material can be processed, and thus graphite square materials can be obtained, expanding the scope of application.
